In some sections, such as those that are environmentally sensitive, we’ll be using Chichester pipeline a trenchless technique called directional drilling. This means that rather than digging up large stretches of ground, Investing in your city’s future we can create small pits from which we can drill underground tunnels to insert pipework. This means less disruption at What about archaeological ground level. finds? Where this is not possible, we will need to cut into the ground to lay pipework.
